WHEEL -HUB.

SPECIFICATION forming part of Letters Patent N0.319,523, dated June 9, 1885.

Application filed October 20, 1884.

To aZZ whom it may concern.-

Beitknown that I, FERDINAND WM. STARR, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Wheel-Hubs, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in wheel-hubs; and it has for its objects, first, to provide in a metallic spoke-socket awooden surface with which the spoke-tenon will come in contact; and, second, to provide in a metallic spokesocket a glue absorbing surface with which the spoke-tenon will come in contact, so as to effect a strong glue-joint.

In the accompanying drawings, forming a part of this specification, and on which like letters of reference indicate the same or corresponding features,Figure 1' represents a longitudinal diametrical section of my improved hub; Fig. 2, an elevation of a portion of the spoke, the edges of two wedges, and the side walls of one of the sockets detached, the same being in section; and Fig. 3, a transverse sectional view of the hub and several of the socket-s, showing one spoke and a set of wedges in position.

The letter A designates a metallic shell or body, preferably malleable cast-iron, having formed integrally therewith a series of exterior radiating spoke-sockets, B. These sockets may be placed in line with each other or disposed so as to form a quarter, a half, or a full dodge, and their side walls, 0, are slightly divergent to each other, whereby a tapering configuration is given to the socket D, as seen in Fig. 3.

The letter E indicates the spokes, the ten ons of which are slightly tapered, the direction being toward the lower ends, whereby they may more readily enter the socket, as will presently appear.

Each socket is provided with two wedges, F, preferably of wood, and of such taper on one side as to agree with that of the walls of the sockets D, and yet to present between their inner faces a configuration agreeing, substantially, with that given to the tenon. WVhen the tenons are not tapered, however, then the inner surfaces of the wedges are paral- (No model.)

lel. These wedges are coated with glue on their inner faces, and the tenons of the spokes are dipped or otherwise coated with glue, so that as the spokes are driven into the sockets the wedges seat themselves firmly and solidly against the walls of the sockets D, while the glue effects a strong union between the wedges and tenons. Owing 'to the fact that wooden surfaces are thus brought together, the glue is found to act more effectively, as well in uniting the parts as in excluding moisture.

The interior of the shell A is designed to be slightly tapering, and is supplied with a correspondingly-tapered wooden core, G, within which is fitted the axle-box H.

All four walls of the respective sockets may, if desired, be tapered or divergently' disposed with respect to each other. The metallic seats of the sockets may also be omitted and the sockets extended to the surface of the wooden core, as seen at Din Fig. 3, in which instance I contemplate coating as well the ends, I, of the tenon as the surfaces thereof, so that such ends may be united by a glue-joint with said core.

Should the metallic sockets be roughened or provided with small spurs on the inner walls thereof, the wedges by being forced laterally against such walls, either during the operation above described of driving the spokes into place, or should the wedges be so forced before driving the spokes in, it will be observed that the roughened surfaces will embed themselves into the wedges. By this means the wedges are held positively and firmly within the sockets. This advantage could not be secured if the wedges were driven longitudinally during the operation of driving.

Having thus fully described my invention, what I claim as new, and .desire to secure by Letters Patent, is'- 1. In a wheel-hub, the combination, with the spoke socket having divergently disposed walls, of the wooden wedges tapered to agree with and fit against said walls, and the spokes having their tenons fitted against saidwedges.

2. In a wheel-hub, the combination,with an outer metallic shell having a series of spokesockets integrally formed therewith,with walls divergently disposed to each other, of the wedges tapered to agree with the sockets, and the spokes having tenons fitted within said sockets and against said wedges, whereby they are provided with wooden pontactsurfaces and against said wedges and core, whereby they the application of glue made more effectual. are provided with wooden contact-surfaces and 3.
